Description

Technical Field

[0001] This utility model relates to the field of bending die technology, specifically a multi-station adjustable automotive parts bending die. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. There are many types of automotive parts. As people's living standards improve, people's consumption of cars is also increasing, and the market for automotive parts is becoming larger and larger. In recent years, automotive parts manufacturers have also been developing rapidly. In the production of automotive parts, a multi-station automotive parts bending die is often used.

[0003] Traditional bending dies rely on manual adjustment of screws, shims, or positioning blocks. Each time the part specifications are changed (such as crossbeams or brackets for different car models), repeated trial and error is required, which can take up to several hours. In multi-variety, small-batch production, the low efficiency of die changing leads to a decrease in production line utilization and an inability to respond quickly to order changes. To address these issues, we have proposed a multi-station adjustable automotive parts bending die. Utility Model Content

[0007] Preferably, a locking bolt is inserted into the upper right side of the base, and locking grooves that cooperate with the locking bolt are evenly distributed on the base. The T-shaped card block is provided with a locking groove that cooperates with the locking bolt, so that the moving plate can be locked by the locking bolt.

[0008] Preferably, locking bolts are inserted at both ends of the mounting plate, and the other end of the locking bolts is inserted into the fixing frame and the pressure block. The fixing frame and the pressure block are provided with locking grooves that cooperate with the locking bolts, so that the pressure block can be installed on the fixing frame through the locking bolts.

[0009] Preferably, the sides of the movable plates that are close to each other are arranged in an L-shape.

[0010] Preferably, there are two sets of the bearing blocks. The bearing blocks are cylindrical in shape. Each set of bearing blocks has a pressure groove on the side that is close to each other, which cooperates with the pressure block. The bearing blocks are movably engaged on the base.

[0011] Preferably, the fixing blocks are all fixedly connected to the bearing block and the base. The two sets of fixing blocks are connected by springs. The lower outer surface of the bearing block abuts against the mounting plate, and the mounting plate is fixedly installed on the base by locking bolts. The bearing block can be reset by springs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a multi-station adjustable automotive parts bending mold, including a base 1, with movable plates 2 connected to the upper left and right sides of the base 1, and a connecting rod 3 fixedly connected to the upper end of the movable plate 2, a fixed frame 4 fixedly connected to the upper end of the connecting rod 3, and cylinders 5 fixedly installed on the upper left and right sides of the fixed frame 4, an mounting plate 6 fixedly connected to the middle position of the lower end of the fixed frame 4, and a pressure block 7 fixedly installed on the other end of the mounting plate 6, a bearing block 8 connected to the middle position of the base 1, and fixed blocks 9 fixedly connected to the left and right sides of the front surface of the base 1, with springs 10 fixedly connected to the side of the two sets of fixed blocks 9 that are close to each other.

[0024] The lower end of the movable plate 2 is movably engaged with the upper end of the base 1 via a T-shaped locking block. The base 1 has a T-shaped slot that mates with the T-shaped locking block. A locking bolt is inserted into the upper right side of the base 1. The base 1 has evenly spaced locking slots that mate with the locking bolt. The T-shaped locking block has a locking slot that mates with the locking bolt. The T-shaped locking block is engaged with the T-shaped slot of the base 1 via a movable engagement method, enabling rapid lateral positioning of the movable plate 2, reducing manual adjustment time. In multi-station molds, different bending positions can be quickly switched (such as left and right symmetrical stations), improving production rhythm. The base 1 has multiple evenly spaced locking slots to support the movable plate 2 in different positions, adapting to the needs of different part lengths or bending angles. The vertical and horizontal protrusions of the T-shaped locking block contact the movable plate 2 and the base 1 respectively, evenly transmitting bending pressure to the base 1 and avoiding local stress concentration.

[0025] Locking bolts are inserted at both ends of the mounting plate 6, and the other end of the locking bolts is inserted into the fixed frame 4 and the pressure block 7. The fixed frame 4 and the pressure block 7 are both provided with locking grooves that cooperate with the locking bolts. The side of the moving plate 2 that is close to each other is provided with an L-shaped structure. The vertical part of the L-shaped plate can be used as a guide post to cooperate with the groove of the fixed frame 4 or the pressure block 7 to ensure that the moving plate 2 does not deviate during the sliding process. The left and right ends of the mounting plate 6 are fixed to the fixed frame 4 and the pressure block 7 at the same time by locking bolts, forming a three-point positioning to avoid loosening caused by single-point force. The plug-in cooperation between the locking bolts and the locking grooves can complete the fixing or disassembly of the mounting plate 6 without tools, shortening the mold change time. The pressure block 7 is connected to the mounting plate 6 by locking bolts and can move synchronously with the moving plate 2.

[0026] Two sets of bearing blocks 8 are provided. The bearing blocks 8 are cylindrical in shape. Each set of bearing blocks 8 has a pressure groove on the side closest to each other, which mates with the pressure block 7. The bearing blocks 8 are movably engaged with the base 1. The fixing blocks 9 are fixedly connected to the bearing blocks 8 and the base 1. The two sets of fixing blocks 9 are connected by springs 10. The lower outer surface of the bearing block 8 abuts against the mounting plate 6, and the mounting plate 6 is fixedly mounted on the base 1 by locking bolts. The symmetrical structure of the cylindrical bearing blocks 8 can evenly distribute the pressure transmitted by the pressure block 7, avoiding local stress concentration that could cause mold deformation. If the part is deformed or damaged, the bearing block 8 is movably engaged on the base 1, allowing it to move or rotate laterally within a certain range to accommodate part positioning deviations or material thickness fluctuations. The pressure groove of the bearing block 8 is tightly fitted with the pressure block 7 to ensure that the bending pressure acts perpendicularly on the part, avoiding angular deviations caused by pressure offset. The tension of the spring 10 keeps the two sets of bearing blocks 8 in a symmetrical position, preventing the mold from tilting or shifting due to unilateral force. The mounting plate 6 is fixed to the base 1 by locking bolts to form a rigid support frame, ensuring that the bearing block 8 will not shift under bending force.

[0027] Working principle: Pull out the locking bolt on the base 1, move the moving plate 2 to the appropriate position, then insert the locking bolt on the base 1 to lock the T-shaped block, place the workpiece on the side where the two sets of moving plates 2 are close to each other, open the cylinder 5, and the cylinder 5 drives the pressure block 7 to move downward through the fixed frame 4, so that the workpiece can be bent.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
